The legislator who withdrew a pseudoephedrine bill from the Senate floor last week has drafted a new version that he thinks will have a better chance of passing. Sen. Robert Stivers, a Republican from Manchester, said Tuesday that his bill would allow people to purchase up to 3.5 grams a month or 15 grams a year of cold and allergy medicines that contain pseudoephedrine or similar ingredients that are used in making methamphetamine. Purchases would be tracked by MethCheck, and those who try to buy more would have to get a prescription. The bill would also prevent those who committed meth-related crimes from purchasing the medicines for five years after their convictions. Stivers said the bill will be heard Thursday by the Senate Judiciary Committee.
